Which iOS browser do you use?

Since I’m a more of a tablet user, my daily devices are iPhone and iPad at the moment. I’m using Safari with AdGuard and private relay, but I was thinking of switching to Vivaldi. AFAIK the engine is practically the same and doing so I would also lose private relay and extensions support. I’ve already ditched other Apple apps and switched to EU services on almost everything (also not Apple related) What do you think? What do you use on iOS?
